While walking on the sidewalk in New York, Steve saw a man dressed in a business suit approaching him and seemingly engaged in conversation with himself. Since people talking to themselves on a public street would usually be among those whose “reality” was a bit different than the norm, Steve became a bit apprehensive. He realized as the man got closer, however, that he was talking on a cell phone using a headset. It was the incongruity of a person who may not be in touch with reality, but dressed in a business suit that sparked the idea for
The telephone was invented in 1875 and patented by Alexander Graham Bell.
Cell phones in the novel
In 1973, ten years before a cell phone was first released onto the market, the first cell phone call was made by Motorola researcher and executive Martin Cooper.3
“The Pulse” is sent out across cell phones in the novel and turns people into mindless killers. Could sound be used as a weapon? Sound waves, when used with high power, are able to unsettle or destroy the eardrums of the intended target. Even less powerful waves have the effect of causing nausea in humans and can cause discomfort. A long-range acoustic device can send messages over longer distances that a normal loudspeaker wouldn’t be capable of. This device has also been used to deter crowds, rioters, and criminals over the past decade. Noise is even more powerful than that, though. Studies have shown that exposure to high intensity ultrasound at frequencies from 700 kHz to 3.6 MHz can cause lung and intestinal damage in mice.4 Sonic weapons aren’t a new invention, though. It is rumored that in World War II, Adolf Hitler’s chief architect, Albert Speer, set up a lab in order to explore his theories of sonic warfare. He created an “acoustic cannon” that worked by igniting a mixture of methane and oxygen in a resonant chamber. In theory, it could create a series of over one thousand explosions per second. This, in turn, could kill someone standing within a one-hundred-yard radius in as little as thirty seconds. This weapon was never actually used, but the consequences of its possible existence are terrifying.
In World War II, during the German siege of the Soviet city of Stalingrad in 1942, Soviet troops kept German forces awake at night by playing Argentine tangos through loudspeakers.5
One thing unique to “The Pulse” victims is that they foam at the mouth. We most often associate this phenomenon with a dog suffering the effects of rabies but is it possible in humans? It is, although it is rare. The most common causes of foaming at the mouth are a drug overdose, seizure, or rabies. Foam is produced when saliva mixes with air or other gases. Because it is so rare, it’s recommended that you seek medical attention immediately if you experience it.
